No one has said it yet, so I guess I will. Have you tried the 3-2-1 method? I usually make baby backs but I have made spares with this method too. Always turns out perfect for me. Just made a couple of racks yesterday that turned out great. What I like about 3-2-1 method is when you foil them during the "2", you add liquid. I save this liquid, I use pineapple juice, garlic, Worcestershire sauce, and a little rub, when the ribs are done. I take the cooking liquid and then reduce it down in a pan until it becomes a thick syrupy glaze. I use this to brush on my ribs the way you used your finishing glaze. I never need sauce for my ribs. When doing baby backs, I usually use 2-2-1 method. I love the way you documented your smoking and it is obvious that others do as well.
Keep it up and we will all look forward to your next smoking session.
